CHARLES F. WILSON,

OF NEW YORK, N. Y.

TROLLEY-WHEEL.

Application filed January 17,

To all whom it may concern:

Be it known that 1, CHARLES F. Wilson, a citizen of the United States,residing in the borough of Brooklyn, city of New York, county of Kings,and State of New York, have invented certain new and useful Imrovementsin Trolley-Wheels, of which the ollowing is a full, clear, and exactspecification, reference being had to the accompanying drawings, and tothe letters of reference marked thereon.

My present invention relates to the construction of trolley-wheels,especially such as are employed on railwaycars for contacting with theoverhead wire and for taking the current from said wire and transmittingit to the electric motor by which the vehicle is repelled.

mong the principal objects of my invention are the reduction of a light,simple, and efficient tro Icy-wheel which may be easily and cheaply madeand which will be strong and durable and afford all the desiredconductivity and to rovide accommodation for means for maintaining aconstant lubrication of the wheel as it turns upon its arbor er" shaft.

To accomplish the foregoing objects anti toi secure other and furtheradvantages inthe matters of construction-and operation, Ew inventioninvolves certain new'and' peculiarities of construction and relative arrangements or combinations of arts, as will he herein first fullydescribed an then pointedlouthin the claims. i

n t e accom anyi aw or part of this speci iicatioli a vertical sectionand elevation of my improved wheel on a plane through the line a: w ofFi 4 and showing the exterior opening throng which the lubricatingmaterialis supplied to the interior chamber. Fig. 2 is a view similar toFig. 1 but on a plane thro h the line y y, 4, showing the openings t o hthe vertic web connected with the hub. ig. 3 7

In all the figures like otters of reference wherever they occur indicatecorresponding parts.

parts which are afterward assembled and se cured to other to constitutethe complete trolley-w eel.

A represents the hub, which carries at or near the central part of itslen th a rejecting web or disk, (represented at l3.) is preferabiy castwith the hub, althou h it might be a plied as a separate piece, an thewe and uh are me e of copper, brass, bronze, or other metal or othercomposition best suited for the purpose of conducting electricity.

The ends of the hub are sli ht'ly reduced, so as to form an abutting lego, as at a ct against which the side pieces may bear, and t e web isperforated, as at b b, to reduce the weight of metal and to formopenings through which lubriating material may pass from one side to theother of the interior chamber. The hub is provided also withperforations, as at c c, for the passage of luhis web' sh a f t; onwhich the wheel may be made to tnrni In'connection with the hub and itsweb I employ'two side plates, as C and D, which arecpreierably similarin outline and are in ten 7 fTh'ese side plates are made of thin metaland ed to constitute the sides of the wheel.

iracy be of malleable iron or of sheet-steel or parts as indicated inFigs. 1 and 2that' 1s, with intfirneidportions d and e, which fittightly upon t e r with. The side plates bear also closely against theouter portion of the web B, but

inside its rounded-out part,-and are secured in place by rivets, as ff,which pass thron h perforations inthe plates and in the web, t eperforations for the rivets in the web being etween the largerperforations b.

The outer portions of the side plates are beaded over or otherwiserounded off, so as not to injure the overhead wire and the groove orchannel for accommodating the wire is rounded out at bottom, the outerportion of the web B being preferably enlarged somewhat, substantiall asindicated, so as to form a complete an perfect bearing for contact withthe conducting-wire.

The side'plates and the web are closely joined, so as to preventleakage-cf lubricating need portion of the hub and agamst the ledges a cto term a close bearing there go volved rapidly,

material at their plates extending through the web, as indicated.

The two side plates and the hub and its web form a chamber E, whichconstitutes a receptacle for lubricating material, such as place ofunion, the side eyond the [)Ol'fOllLtlOl'lS oil or plumbago or othersuitable substance or mixture. .This chamber being charged withlubricating material, the latter finds its way to the arbor or shaftthrough the perforations ct When the wheel is being reas it is while itis traveling on the conducting a wire, the tendency is always to throwthe lubricating material away from the hub, and thus to prevent theconstant lubrication which is desirable. To overcome this disadvantageand to carry a small portion of the lubricant to the hub, I supply thechamber with loose rings, one or more, as F F, one on each side of theweb and around the hub, these rings being of diameter considerablygreater than the exterior of the hub. The rin s F F reach well out tothe outer extremity 0% the chamber, and as the hub turns they travel incontact with it, carrying a portion of the lubricant from the outermostart of the chamber in contact with the hub, and thence it flows throughthe orifices provided for the purpose in the hub and into contact withthe stationary arbor. At 9 through one of the side plates is acharging-orifice, and this is kept normally closed by a spring h, whichcarries a projection fitting the interior of the orifice g and operatingto confine the material within the c amber and to prevent entrance ofdust or foreign matters. The spring is secured on the inside of one ofthe plates before it is mounted in place. To charge the chamber, it isonly necessary to insert the nozzle ofthe charging-can through theorifice g, which operation forces the s ring it back and permits thenecessary fiilin after which the charging-orifice is automaticallyclosed.

The side plates bein of much less expensive material than theIi rovedtrolley-wheel can be made at much less cost than if cast solid of theusual conducting material. The side plates being made of more durablematerial than that ub and web, the im-.

usually employed in the solid wheels, the lll'l])I'(JVO(l wheel willlast longer than the solid wheel. The constant supply of lubrieatingmaterial will also tend to enable the improved wheel to run for a longertime than the solid constructions.

The trolley-wheel constructed and. arranged for operation substantiallyin accordance with the foregoingexplanations will be found to admirablyanswer all the purposes and objects of the invention hereinbeforealluded to.

Having now fully described. my invention, what I claim as new herein,and desire to secure by Letters Patent, is

In a trolley-wl'ieel, a hub carrying a projecting web and reduced at itsends to form abutting ledges, and two side plates com-' bined with saidhub and web, the plates having inturned portions fitting the reducedportions and bearing against the ledges, the parts being securedtogether, substantially as and for the purposes set forth.

2. In a trolley-wheel, the combination with the hub and Web, of the twoside plates secured thereto by rivets as explained and forming a chamberfor lubricating material, the outer portion of the web being enlargedand rounded out and the side plates contacting with the web inside ofthe rounded-out portion, substantially as and for the purposes setforth.

3. In a trolley-wheel, the combination with the hub and web, of two sideplates secured thereto, the said web being provided with the marginalrounded-out portion and with openings as explained, the side platescontacting with the Web beyond the margins of the openings and insidethe rounded-out portion and secured by rivets passing through the webbetween the openings, substantially as and for the pur oses explained.

In testimony whereof I lihve signed my name to this specification in thepresence of two subscribing witnesses.

CHARLES F. WILSON.
